The Disk Location plugin does this on the multi-disk summary display. It also displays the current temperature of each drive, regardless of whether they are spun up or not.
You're trying to run a load of plugins - they are reported as corrupt .tar files - perhaps due to lack of RAM when trying to unpack them. You are running and trying to install just about every option from the Nerdpack - that will be taking a chunk of space. They idea of Nerdpack is to only enable the features actually required. After that is installed just about everything else has problems. If you look through the text file yourself you can see this. I still think this is primarily a lack of RAM. Certainly I would not expect to run any plugins reliably when you have only half the recommended minimum RAM available. First thing I would try is to borrow a bit more RAM from somewhere just to see if that helps - and uninstall Nerdpack, or at least limit the modules that you are enabling.
